I have been playing with electrochemistry for a while now, mainly with aluminium, hydrogen and iron electrochemistries. I have not had much success with the aluminium chemistry, holding little more than half a volt, albeit for several weeks, extending into months now. I have had much more success with iron, my latest prototype (going in a self discharge test) has been going for weeks now, holding at a little under 1.2v open circuit voltage. I have no nickel, so nickel iron testing is out for now, and I posses no non metals nor ionic compounds that would make an active cathode, so it just uses inert graphite. I have not done any loading test for the iron one yet though, I suspect that it has very poor current capability and there will be loaded voltage drop as well.
I want to start on a dual carbon cell, as it looks like there are plenty of ionic compounds to try, I will likely experiment with sodium acetate first. Might or might not work.
Are there any ideas as to other electrochemistries that I could try? I want to try new methods, making new designs that haven't been thought of or generally tested yet, but also avoiding the production of halogens at the same time as well!
